Living in GSP as I do, you get to see a lot of express ops. I was wondering what everyone thinks of the various operations around the US- here's my opinion.

American Eagle
DFW-The A2 Terminal's awful if one has tight connx to mainline in Terminals B and C, but the facility itself is nice.
ORD-First class express op,UAX/ACA should take a hint.

Continental Express
EWR-The old cattle style system was awful, but now arrivals on ERJs are into the main terminal, just like mainline.
CLE-Terminal D is nice.
IAH-Haven't been here yet.

Delta Connection
ATL-ASA's Terminal C operation is awful, cramped and crowded.
CVG-Another first class op, except for the fact one has to be bussed to Terminals A and B.
SLC-Haven't been there.
DFW-haven't been there.

Northwest Airlink
MEM-nice facility after renovations.
DTW-haven't been to midfield yet.
MSP-haven't been there yet

US Airways Express
CLT & PHL- Both are brand new and I haven't been to either
PIT-decent if you get into the main terminal, E is okay but the train's a hastle

United Express
IAD-when we went through the A part of the facility was nice, though connx from T gates are bad(people movers) and connx to Concourses C and D suffer from same problem.
ORD-F gate area's a disaster, the infrastructure simply doesn't exist like AE's Concourse G, it's probably the worst express operation in the nation.
DEN,SFO,LAX-Haven't been through.

As you can see I haven't been through most of the Western hubs, would like opinions.
